Is the size and speed/gravitation of planet earth not important when calculating force/mass/velocity/gravity levels of individual "entities" and calculations? Am i wrong to question our continuance of linear 1 dimensional equations? hmmmmm

Size is important (as in mass and dimension), speed is important (as in velocity and direction). Newtonian Gravitation addresses these variables with great precision. At extreme values of mass or extremes velocities there are other factors that must be accounted. For example the Advance of the Perihelion of Mercury, always touted as one of Relativity’s great successes, stems from the relative velocity of a planet contrasted to the speed of light.

Yes. It is important. As are things such as air resistance, gravitational variances, Coriolis force, differential velocity, tidal forces, etc. etc.
But these are 2'nd, 3'rd, and 4'th order factors. For purposes of teaching basic concepts, it's easier not to have to worry about them initially.

As ong as the calculations on near-earth(surfacE) entities are concerned size of earth vel. etc can safely b neglected
